Hi,
I have a REST service based on JAX-WS Provider and Dispatch (implementing
Provider<DataSource>). Until now, I accept/produce only XML. Now, I have to
support attachments.
Now, it seems like request should be "multipart/related" as only
AttachmentInInterceptor is part of the chain by default. I could probably change that to
use AttachmentInputInterceptor instead. The question is how can I can I return
MultipartBody? Is there in-built support for that or should I create my own DataSource
and handle with an custom out interceptor?
Adding @Consumes("multipart/related") should be enough to get DataSource
representing the root attachment, and similarly adding
@Produces("multipart/related") is nearly enough to get out DataSource
converted to the multipart payload, except that you also need to specify
the content type of this root type, so it can look like this:
@Produces("multipart/related;type=application/xml")
@Consumes("multipart/related")
public DataSource a(DataSource ds) {
return ds;
}
My understanding you'd like to have a 100% portable code, right ?
Note that up to CXF 3.0-SNAPSHOT, the input 'ds' parameter will
represent the root part of the incoming payload. The response DataSource
also represents the root part of the outgoing attachment.
I think it is rarely that someone will want to have 'ds' (in this case)
representing the actual non-parsed multipart payload or manually build
the actual multipart body, so originally I went that path.
In CXF 3.0, due to JAX-RS 2.0 TCK 'insistence' on the types like
DataSource, InputStream, byte[] be supported by basic pre-packaged
providers, the above will slightly change to:
@Produces("multipart/related;type=application/xml")
@Consumes("multipart/related")
@Multipart
public DataSource a(@Multipart DataSource ds) {
return ds;
}
Where CXF @Multipart annotation marks in and out parameters as multipart
bodies. Without @Multipart the 1st example above will produce a portable
but more complex code (meaning DataSource will have to be manually
parsed or used to create the out payload manually)
